This invention relates to a bookstand, and is more particularlyconcerned with the design and construction of a bookstandl whereby thebook is adequately and'positively braced, andmay be pulled towards oraway from the reader at Will.`

An object of the invention is to devise a new and improved rotatable'bookstand Another object is to producev a new and improved bracing forabookstand. Anotherobject is to produce a-new form of page clamp foraboolrstand. j

`Another object is to produoe a new form of rotatable rod together withmeans for inserting and holding said rod, the) said rod containing thepage clamping elements of a bookstand. i j i 1 i i i Another. object istouproduce in a bookstand having ajbase member and a hook holdingmember, a new and improved form of clamping means forsecuring the bookholding member to a cooperating arm.

Still another object is to produce `a new form of union between thetelescoping arms of a bookstand whereby onel of the arms has limitedangularmovement With respect to the other. i Vj' i A Other objects willappearr hereinafter. i

In operation, one foot 3 is placed'underneath the chair or similardevice 20', while the other extends outwardly from the side thereof.VVhen the reader is using a heavy book for a reference, he may pull theplatform V19 and arm 8 towards him intoa reading position; While When hedeslres to jotV transverse' members 20 joined at their outer endsby'cross members 21 and 22", preferably of tL-section.

Fitted intothe rod 28, which may be of wood orother suitablema- Vterial, are page-clamps 31 and 32'7 having` linturn'ed portions 33and 34, respectively,

which may, by rotation of the rod 28, be moved into or out of lelampingrelation with arb'ook held on'theplatform'l.` VVhen turning' the' pagesof a book, it is necessary onl-y tomove the rod 28 to the leftfto clearthe'pin j 30 andI to thenr0tate it outwardly so that ft'he clamps will?assume'the position indii eated-in dottedoutlinefin' Fignl 2' The Vpagesmay then be turned, after which the revers operation is employed torestore the clamp members to their operative position. It is understoodthat any other clamping means may be employed without departing` fromthe spirit of my invention.

The rod 8 is shown as having a transversely or horizontally extendingportion 35 to which the platform 19 may be adjustably secured in anysuitable manner. As shown, the clamp member 36 is adjustablyA secured tothe'rear of the platform 19, preferably along the central transversemember 23. vA headed bolt 37 extends rearwardly fromthe member 23) andadjustably secures one extremity offthe elamp'member 36, while' anotherheaded bolt 38 performs a similar function at the opposite endthereof.S'uitable recesses'39- and 40 are provided in the clamp member 36 andtransverse memberv 23, respectiveliy', to adapt the same to the contoursof thel farm V35. Means such as a headed bolt' 41 leXtends through theclamp member 36,V into opera'tive relation with the arm 35,- to clampthe' member thereto.- By simultaneously adjusting the' bolts 38 and 41,the bolt 37 being left in a fiXed position, it is possible to tightentheV clamp platform`l9 to the arm 35. By this mechanism, the platformmay be Vplaced in any desirable angular relation with 'respect to itssupporting armand-to the reader. It

is apparent of course, that this construction 'may be variedi at willwithout departing from -the'scope of the invention.-
